I would A because if you do 16+18 that is 34 and the teacher would only be choosing one girl. So I think it is A. I’m sorry if this is wrong! Have a great day!

Aliun [14]

Answer:

The mode of the following number of countries randomly selected travelers visited in the past two years is 13.

Step-by-step explanation:

The mode of a data-set is the value that appears the most commonly, the most frequently.

In this data-set:

13 appears 3 times

7 and 4 twice

What is the value of x?<br> What is the measure of angle QOR?<br> What is the measure of angle ROS?

Veseljchak [2.6K]

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

$(x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26$

Sub x in

$(x + 5) \\ 26 + 5 = 31$

and

$(2 \times 26 + 7) \\ = 52 + 7 \\ = 59$

Determine the value of x if (211) base x = 152 base 8

tekilochka [14]

It's the same as x^211 = 8^152

Simplify that equation. Find the 211th root of (8^152), and that is what x equals. If I remember logs correctly...
